Area Forecast Discussion
National Weather Service Northern Indiana
130 AM EDT Thu May 17 2018

.SYNOPSIS...
Issued at 747 PM EDT Wed May 16 2018

Mostly dry weather with slightly above average high
temperatures is expected through Thursday. As the weekend
approaches, chances for showers and thunderstorms will be on the
rise with the great chance on Sunday. With the arrival of the
next work week, the transition back to dry and seasonable weather
begins.

&&

.SHORT TERM...(This Evening through Thursday)
Issued at 300 PM EDT Wed May 16 2018

High pressure overhead today slowly moves east away from the
region by the end of Thursday giving way to a cold front for early
Friday. This setup will continue to provide mostly dry conditions
around the region for the overnight tonight into Thursday.
Tonight, with a lack of clouds around and light winds, some
shallow drainage fog may form, but it`s low confidence at this
time, especially now that we are one day away from any soaking
rain. Thursday highs are expected to be in the upper 70s to low
80s.

&&

.LONG TERM...(Thursday Night through Wednesday)
Issued at 300 PM EDT Wed May 16 2018

A cold front washing out enters early Friday allowing for cooler
temperatures on Friday with 70s for highs. At the same time,
moisture pushing north from the south will allow for showers as
well as possibly a thunderstorm mainly east of I-69 to end the
day.

The energy associated with this moisture will start moving out of
the region on Saturday ahead of a trough coming in later Saturday
night into Sunday. A wave may form along this trough and push a
warm front into the region. Depending on how far north this front
can come in, some instability may be able to come in and, coupled
with appreciable shear, some thunderstorms are possible Sunday
afternoon/night.

Monday is expected to be the transition day with any lingering
showers ending as high pressure returns. The jet stream shifts
north of the area and things dry out for Tuesday and Wednesday.

.AVIATION...(For the 06Z TAFS through 06Z Thursday Night)
Issued at 130 AM EDT Thu May 17 2018

VFR conditions to persist through the period as dry low level
ridge settles over the region. Any precip/lower clouds will remain

afternoon with a few gusts around 20 kts possible.
